Long Answer type Questions

Question 10
What are magnetic and nonmagnetic Materials

Answer

Magnetic Materials
Materials that are attracted by a magnet are called magnetic materials. Objects made of materials such as iron, cobalt and nickel are magnetic objects
Non-Magnetic Materials
Materials that are not attracted by magnets are called non-magnetic materials. Examples of non-magnetic materials include rubber, wood, feather etc



Question 11
What are different type of magnets? And where are the poles located?

Answer

Bar Magnet
the poles are located at the ends of the bar
Horseshoe Magnet
the poles are located at the two free ends of the 'U' shape.
Cylindrical magnet
the poles are located at the two circular ends of the cylinder


Question 12
(i)How should we store magnets?
(ii)Write two methods by which a magnet can be demagnetized.

Answer

(i)Bar magnets should be kept in pairs with their unlike poles on the same side. They must be separated by a piece of wood while two pieces of soft iron should be placed across their ends. For horse-shoe magnet, one should keep a piece of iron across the poles.

(ii)
(1) By hammering the magnet strongly.
(2) By heating a magnet strongly and keeping it in the east-west direction.


Question 13
A bar magnet has no markings to indicate its poles. How would you find out near which end is its north pole located?
It is advised to keep the magnets away from television, mobiles, CD and computers Explain why?

Answer

(i) Take the bar magnet and suspend it freely with the help of a thread, the end that points towards north pole will be regarded as north end of the magnet. Take a bar magnet with known/marked poles on it. Let the north pole of the magnet be brought closer to the suspended magnet at the end that is pointing towards north, if it shows repulsion than it is confirmed.
(ii)Television, mobiles, CD, computers and many more devices are made up of magnetic materials and magnets in it. If you bring a magnet closer to it then it will spoil these devices.


Question 14
(i)Write main properties of a magnet.
(ii)Draw a diagram of a magnetic compass.

Answer

(i)

  1. Magnet has two poles—south pole and north pole.
  2. Poles of magnet cannot be isolated.
  3. Like poles repel each other and unlike poles attract each other.
  4. Freely suspended magnet aligns in N-S direction.
(ii)


Question 15
ONE WORD ANSWER.
i.Name a material used for making a permanent magnet.
ii.If a bar magnet is cut into equal pieces by cutting it at right angles to its axis at two places, then how many bar magnets will be formed?
iii.What is natural magnet called?
iv.What is the instrument in which directive property of a magnet is used?
v.At which place on a magnet, its magnetic force is maximum?

Answer

i.Steel
ii.three
iii.Magnetite
iv.Mariner’s compass.
v.At poles.


Question 16
VERY SHORT ANSWER.
i.What is a temporary magnet?
ii.What happens when N-pole of a magnet is brought near the N-pole of a suspended magnet?
iii.Which is the South Pole of a bar magnet?
iv.In which direction does a suspended magnet come to rest?

Answer

i.It is piece of magnet only for a short period. This magnetism is lost as soon as the source of magnetization is removed.
ii.There is repulsion between these two magnets as there is repulsion between like poles.
iii.It is the tip of a bar magnet which points towards the south direction.
iv.Magnet comes to rest in N-S (north-south) direction.
